To Underworld

Xin looked at the train station going to Underwood, he did not expect that it was actually built under the school.

It was huge like the train station in the twon, much more the luxurious-looking Train, it also has the Gremory Clan Logo.

Issie amaze in what he sees," Little Master, are we really going to the Underworld raiding this cool looking train?"

"That's right, this is the only transportation except for magic in going to the Underworld," Xin said.

Rias said," Okay let's enter, my clan have a private room that we can use"

Xin then looked at Azazel and asked," So why are you coming with us? Azazel-sensei"

"Azazel-sensei!" They were shocked that they did not notice Azazel coming with them, they only realized when Xin called him.

Azazel grin at them and said," You guys need more training, I already following you but you guys did not even notice my presence"

"And I'm going to the Underworld to attend a meeting so you guys can enjoy your vacation," Then Azazel teleported somewhere.

"Okay let's go, we still have a lot of time before arriving in the Underworld," Rias said, bringing all of them inside of the train.

Xin sigh and said," Melan, can you put me down now, we are already inside"

Melan who hugged Xin in front like a doll said," No….. Master is in weak form…. Melan will protect Master from every danger…. "

The danger that she is talking about is not that dangerous like the Kahos Brigade but the girls who want to hug Xin like a doll.

In the morning Rias and Akeno are already sleeping with Xin. They use him like a doll the whole night because they install a cooling system inside of the house. He les them sleep with him and hug him too.

In the morning Koneko and Asia take turns playing with Xin, they even take care of Xin 's needs.

In the evening Xenovia and Ravel take turns playing with Xin, sometimes they help Xin in making Sacred Gear by using it in the experiment.

And Melan can only take Xin when it's time to bathe or if they're going to raid a base of the Khaos Brigade.

This cycle continues for a week.

And Melan eventually fed up with them, she also wanted to solo his master so early in the morning she did not put down Xin. She kept insisting on holding him like a doll.

Inside of the train Xin and the girls playing with cards, they do this to kill some time and of course to see how strong in card Xin really is.

Kiba takes a card to Issei and gets No. 7, he puts the pair of N0.7 in the table.

Issei reached the card of Koneko and got a No.4 he was unlucky this time he did not get any pair.

Koneko pick card to Xin's hand and successful got a pair of a card, Xin look at his card and pick a card to Rias hand

He successfully got a pair too, then put it down on the table. He looked out the window and said," So this train is traveling inside of the dimension gap?"

Rias who is picking card to Akeno said," This right this train travel inside of the dimensional gap"

"There are 2 types of the meaning of transportation in the underworld, the first is using magic, you need a devil who can travel in the dimensional gap using magic"

"And the second is by using this train that travels in the underworld"

"And this train station will stop in Sitri Clan," Akeno said while choosing a card in hand of Ravel.

Rias looked at Xin and said," By the way, did Sona already come at you?"

Xin helpless said," No, after she cry she did not come again"

"I can't still believe that proud girl actually cries because she loses in every game you play," Rias mischievous said.

She know how prideful Sona is, she will never stop until she defeat you but who expect that Xin is good at playing games.

Even though she and Sona group together they can still win against him, and after losing for 5 straight days Sona gives up and cries.

Xin who looking at his card suddenly smile," The cry baby arrives"

"Cry baby?" They are all confused until the door of their room opens. They all see Sona, Saji, and Tsubaki entering inside.

"Hello, Rias and X-Xin," Sona said while looking awkward greeting Xin.

"Hello, Sona, did you stop pouting like a little girl and you actually greet us here?" Rias can't help but tease her after that embarrassing accident happens.

"I-I did not cry, I-I just remembered something so I cried that time," Sona embarrassingly said, trying to fool them but she couldn't.

All of them see her cry at that time, and then she run after Xin defeats him in another mind game.

*Cough

Sona said," We are about to get near in Sitri territory so we are going first"

"Sure, we will going to see you guys in the gathering of devil next week"

"Okay see you guys there," Then she look at Xin and flustered said," Y-You can also come to my home later X-Xin"

Xin look at her and smiled," I thought that you're going to forget me because of that game"

"No I'm not simple-minded like that, i can easily accept my lose but nott forever, I will defeat you later"

Xin smiled brightly," Good, i will remember that Sona-oneesama ~"

Sona's face becomes beef red hearing how he called him, she somehow understand why her sister always bothered him.

It's not because she want to bother her but because she likes hearing him calling her like this.
